For what its worth regarding corrupt BOOT0/1 with Mariko (SX Core):
I tried quite a few methods but in the end using NxNandManager_x64.exe worked for me. Dumped my 11.0.1 (i think) sysNAND boots via USB mounted through Hekate and wrote them to my 10.2 emuNAND with my SD card directly in the PC (not via mounted USB Hekate).. Point being they are on different versions, still worked and some methods didn't work for me.
I did quite a few different methods/combos, but i think this is what worked for me.
Then I upgraded to Atmos18 and broke Tinfoil (all nsp games work though)
